Application filed December 2,1392. Serial in. 453,851. (No as.) Patentedin France May 9, 1892, in. 221,468, and in England November 9,1892,N0.20,222

To aZZ whom it may concern:

Be it known that I, ALPHONSE GUTTIN, a

citizen of France, and a resident of Paris, in the Department of theSeine, have invented a new and useful Improvement in Feeding Mechanismfor Wire-Nail-Making Machines, (for which I have obtained a patent inGreat Britain, dated November 9, 1892, No. 20,222, anda patent inFrance, dated May 9, 1892, No. 221,468,) of which the following is aspecification.

This invention relates to apparatus or mechanism for feeding orpropelling the Wire in nail making and other like machinery and is moreespecially designed for use in connection with machinery employed in themanufacture of nails of the class known as horseshoe nails. In forgingnails of this description the wire requires to receive two blows withwhich two separate feed motions of the wire must correspond but themechanism operating to form the nails forms no part of the presentinvention and may be of any known or suitable construction. Theinvention is altogether independent of this mechanism and relates to anapparatus which imparts to the wire two feed movements which may be ofunequal length and enables these two unequal feed movements to berepeated as often as required. The apparatus may be employed in anymachineryin which it is necessary to intermittently propel or feedforward a wire with forward movements alternately of unequal amplitudemeans being also provided for regulating the amplitude of the saidmovements. And in order that the said invention may be fully understoodI shall now proceed more particularly to describe the same and for thatpurpose shall refer to the several figures on the annexed sheet ofdrawings the same letters of reference indicating corresponding parts inall the figures.

Figure l of the accompanying drawings represents in elevation an exampleof an apparatus constructed according to this invention and Fig. 2represents the apparatus in plan. Fig. 3, is a side elevation of themachine. Fig. 4, is a plan view of the same.

Motion is imparted to this apparatus by a driving shaft at A Fig. 2which is provided with a spur-gear A, meshing with a spurpinion A Uponthe d riving-shaftA is keyed a cam B having two offsets or projections,b

b, and a bevel gear wheel 0 keyed upon the driving-shaft A and meshingwith a similar bevel-gear C (Fig. 2,) upon a shaft W, lying at rightangles to the driving-shaft A. A bell crank lever D constantly actedupon by a spring V tending to press its upper arm which is provided witha friction roll or rider or, which has journal-support upon the end ofsaid upper arm against the cam B is displaced from its normal positionof equilibrium by the passage of the ofisets on the cam being movedtwice in each complete revolution it of the shaft A. Thelever Dtransmits motion to a connecting rod-E and thereby causes a lever F tooscillate upon its center or rock shaft F. This movement of the lever Fcauses the upper extremity of the said lever to act upon and rock ashort arm or lever S (see Fig. 2) pivotally attached to a carriage G andcauses a jaw O on the said lever S to nip the wire (indicated at N)between it and a corresponding jaw on the carriage G. The continuedmovement of the lever F causes the carriage G and wire N to move forwarduntil the front end H of the carriage comes in contact with thestationary guide or stop K. The distance between the end H and the stopK regulates the amplitude of this movement of the Wire. The carriage isafterward moved back by the action of springs P Q and the stress of thespring V causes the lever F, rod E and lever D to return to theiroriginal position after the passage of the first offset on the cam B,the lever D being maintained in contact with the cylindrical part of thesaid cam. At this period a shaft W rotated by the gearing 0. causes alever M to oscillate on its center or fulcrum m. This movement isproduced by a grooved cam L fixed on the shaft NV and causes the supportof the carriage G to move to the left hand in the drawings the saidsupport being formed by a horizontal shoe or slide I provided with twovertical arms or uprights J. The jaw 0 being open when this movementtakes place the wire is not moved forward but the distance between theend H of the carriage G and the fixed stop K is diminished by an amountequal to the forward movement of the support I J supporting the carriageG. Consequently when the second offset on the cam comes into action ashereinbefore explained and feeds forward the wire N the amplitude ofthis second forward movement is less than that of the precedingmovement. Continuous rotary motion being imparted to the shaft A thewire is consequently fed forward intermittently with alternately longand short movements which can be regulated by adjusting screws providedon the connecting rod E at U and T and by means of a set screw Rregulating the movement of the support I J. In working this apparatusthe wire N being drawn from a reel or'bobbin is passed between the jawson the lever S and carriage G and rotary motion is imparted to the shaftA. One of the offsets on the cam B comes in contact with the lever D andthe-connecting rod E causes the lever F to oscillate upon. its fulcrumthereby first closing the jaw 0 upon the wireand secondlymovingforwardthe carriage G and wire N until the carriage comes incontactwiththestopK. Theoffsetonthecamthen leaves the lever D and theparts are returned to theiroriginal position (indicated in Fig.1) by theaction of the springs V, P and Q. The cam groove L then acts upon thelever M which vibrates and moves forward the support IJ of the carriageG so as to diminish the distance between the latter and the stop K. Thesecond offset on the cam B then acts uponthe lever D in a similar mannerto the first offset and a second forward movement of the wire takesplace.

Upon a bracket N on the machine frame, is fulcrumed a lever N, one endof which is provided with a friction-roll n, which rests upon the cam Band receives the thrust of the cam-projections b, b. The other extremityof said lever produces the series of pressures by which the faces of thenail are formed. Upon a shaft P (Fig. 4) is mounted a gear P meshingwith a gear P on the power shaft A. At the end of said shaft is mounteda cam P which engages the end of a lever Q, the other end of the latterbeing connected to a slide Q carrying the movable knife, or cutter, forsevering the nails. The rigid support Q carries the fixed cutter. Theamplitude of this second movement is less than that of the first owingto the distance between the carriage G and stop K being reduced. Thiscam groove L then returns the lever M to the position indicated in thedrawings in Figs. 1 and 2 the shaft A having described one completerevolution and the same series of movement is repeated at eachrevolution of the said shaft.

Having now particularly described and ascertained the nature of thisinvention and in what manner the same is to be performed, I declare thatwhat I claim is- 1. In an apparatus for feeding wire in nailmaking andother like machinery, in which two unequal forward or feed movements areimparted to the wire at each revolution of the drive-shaft, thecombination with the driving-shaft, of a cam mounted thereon, abellcrank vibrated by said cam, a lever vibrated by said bell-crank, amovable carriage provided with a fulcrum for said lever, a jaw operatedby the lever to clamp the Wire upon a jaw on the carriage, and means forvarying the amplitude of the movements of said carriage, substantiallyas described.

2. In an apparatus for feeding wire, the combination with adriving-shaft and with a driven shaft at right angles thereto, of bevelgearing connecting the same, a cam on the driving-shaft, a bell-cranklever vibrated by said cam, a lever vibrated by said bell-crank, a feedcarriage having a jaw to engage the wire, a jaw-actuating leverfulcrumedon said carriage, and connected to the bell-crank lever, and stops forlimiting the feed-movement, of the carriage and for varying theamplitude thereof, substantially as described.

3. In an apparatus for feeding wire, the combination with a drivingshaft and with a driven shaft at right angles thereto, a bevel gearingconnecting the same, a cam on the driving shaft, a bell-crank leverreciprocated by said cam, a lever vibrated by said bellcrank, afeed-carriage having a jaw to engage the wire a jaw-actuating leverfulcrumed on said carriage, and connected to the bell-crank lever, andalever fulcrumed upon the support for the feed-carriage, one end of saidlever having engagement with a cam-groove formed in a device mounted onthe driven shaft, and its other end having an adjustable connection withthe movable supports of the feed-carriage, substantially as described.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.

ALPI-IONSE GUTTIN.
